Definitions
- the implants of the present invention are structurally adapted, such that when properly inserted, the length of the lateral side wall as measured from the leading end to the trailing end is of a lesser length than the length of the implant along its mid-longitudinal axis so as to prevent the protrusion of the lateral side wall and trailing end junction beyond the circumferentially curved profile of the vertebral bodies.
- a complementary implant 100 is inserted by allowing it to rotate within the maximum circumference of implant 200.
- Pre-tapping the bores formed across the disc space prior to the insertion of the implants does not deviate from the present teaching.
- pre-tapping is not required as certain preferred embodiments of the present implants are tapered from their trailing to their leading ends and the leading ends have particularly significant thread heights making their ability to thread themselves into the bone particularly effective.
- Figures 11-14 show openings at the trailing end of the implant for receiving opposed screws that may be oriented from the implant into each of the adjacent vertebral bodies.
